Product Number: ADAR2001
Hi, ADI Expert:
We are using ADAR2001 for our project. We are stuck in the register configuration part. We hope to get your assistance.
We use "SPI CONTROL" mode and below is our register configuration:
ADAR2001_Write(ADAR200x_SCRATCH_PAD, 0x35);
scratch[0] = ADAR2001_Read(ADAR200x_SCRATCH_PAD);
if(scratch[0] != 0x35) while(1);
ADAR2001_Write(ADAR2001_TX_SEQUENCER_SETUP, 0x00); //set register 0x16
ADAR2001_Write(ADAR2001_MULT_SEQUENCER_SETUP, 0x00); //set register 0x18
ADAR2001_Write(0x10, 1);
ADAR2001_Write(0x13, 0xff);
ADAR2001_Write(ADAR2001_TX_EN1_SPI, 0xFF); //set register 0x45, 0x55 also configured
ADAR2001_Write(ADAR2001_TX_EN2_SPI, 0x07); //set register 0x46
ADAR2001_Write(ADAR2001_MULT_EN_SPI, 0x6E); //set register 0x47
ADAR2001_Write(ADAR2001_MULT_PASS_SPI, 0x9F); //set register 0x48
But we find that No matter how it was configured, it was found that the power consumption of the ADAR2001 chip remained unchanged. This does not match the manual, so we suspect that there might be some other areas that have not been enabled.
PS:
We have conducted multiple checks on the SPI communication and it is absolutely fine. The external voltage input of 2.5V and the 1.8V output of VREG are also normal.
